Abstract
The photocatalyst(DPPBI/Pt/TiO2)was prepared using N,N'-di(4-pyridyl)-3,4,9,10-perylene tetracarboxylic acid bisimide(DPPBI)sensitized Pt/TiO2 and characterized by infrared spectroscopy(IR),UV-Vis diffuse reflectance spectroscopy(UV-Vis DRS),scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS),and X-ray diffraction(XRD).The results of characterization showed that the crystal form of TiO2 was anatase,Pt was highly dispersed on the surface of TiO2 and DPPBI was adsorbed on the surface of Pt/TiO2 in DPPBI/Pt/TiO2.Hydrogen production from water splitting using photocatalyst(DPPBI/Pt/TiO2)was studied.It has been found that the rate of hydrogen evolution reaches 6.69 μmol·h-1·g-1 under visible light irradiation for 8 h with 300 W Xe-lamp cold light source when 250 mL reactive liquid contains 0.8 g·L-1 photocatalyst(0.1% DPPBI/0.4%Pt/TiO2)and 0.2 mol·L-1 KI.
